I know there is an old 2022 thread about this but I thought I would bubble it up to the top as SeatGuru info is Very Out of Date now. And there is nothing to indicate that on their website. I only noticed it as it was missing a particular plane for a carrier I wanted to check out the seat chart prior to possibly buying a ticket on that flight.
I contacted them to ask for an add of that plane for that carrier.
This is the answer I got back from them:
Thank you for your interest in SeatGuru. Currently we are not making additional updates to our content on the site and are unable to provide other support. -SeatGuru
It almost seems criminal that are not posting that on the main page! They are definitely getting ad revenue from those pages!
